Abstract (en)
[origin: EP0436496A1] Keys for lock cylinders containing a rotatably adjustable cylinder core having a key channel opening out freely on its circumferential surface, especially of lock systems, are equipped with a profile region (2), which faces the key spine (1) extending flush with the cylinder-core circumferential surface in the key-insertion position and which is to be provided laterally with longitudinal profiled grooves (3, 3'), and with an incision region (5) which faces the opposite key breast (4) having the key stop (4') and which is to be provided with milled cuts, countersinks or such like incisions (6) for the allocation of the tumbler elements present in the lock cylinder. <??>To improve the key in terms of stability in its incision region (5) and also with a view to an even larger number of possibilities for accommodating its incisions (6), whilst at the same time preserving its profile region (2) allowing variable profiled grooves to be formed, the incision region (5) has an essentially circular-cylindrical shape and is made wider than the profile region (2) of the key. Advantageously, at the same time, the height (H) of the profile region (2) exceeds that (h) of the incision region (5), as seen in the radial direction. <IMAGE>
